trapping

trapping,

most broadly, the use of mechanical or deceptive devices to capture, kill, or injure animals. It may be applied to the practice of using birdlime to capture birds, lobster pots to trap lobsters, and seines to catch fish. Usually, however, trapping means the capture of land animals larger than rodents by means of deadfall, pitfall, and, especially in modern times, spring-snapped, steel-jawed steel traps. In societies where hunting and fishing are the staple occupations, trapping is used to supply food and, in colder climates, furs for clothing. Since antiquity trapping has been the basis of the fur trade (see furfur,hairy covering of an animal, especially the skins of animals that have thick, soft, close-growing hair next to the skin itself and coarser protective hair above it......Click the link for more information.). It still occupies a great many people over large sections of the globe, especially in the colder regions, such as N Siberia and N Canada. Trapping has also been used to rid an area of animals thought to endanger the lives of human beings or domestic animals. Spurred by bounty laws, the practice of trapping in the United States in the 19th cent. helped lead to the extinction or near-extinction of many mammals, such as various species of bears, mountain lions, wolves, and coyotes. Modern game management frowns upon trapping and recognizes the importance of predators in the ecosystem. Such trapping as is permitted today in the United States is strictly regulated by law.

[′trap·iŋ]

A method for intercepting a reactive intermediate or molecule and removing it from the system or converting it to a more stable form for further study and identification.

This book treats public political events in America between 1788 and Jefferson's election in 1800, including parades and other open air occasions, as well as accompanying festivities and trappings, including dinners, the raising of liberty poles, ceremonial toastings, songs, badges, etc.

Control of the streets for such events might literally depend on the threat of coercion, and many warlike trappings were likewise used by paraders.

Animals recaptured in subsequent trappings are measured and sampled again so that changes in numbers of animals, body growth rates, movement, reproductive condition, and infection status can be monitored.
